Outline of Final Research Achievements

This research studied estimation methods for execution times of target systems. First, system level description methods for target system were surveyed, then this study proposed a fast and efficient estimation method by using considered system level descriptions. Furthermore, this study proposed more efficient estimation method using stochastic execution information of tasks by input data variability.
